(Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) The invention described hereinmay be manufactured and used by or for the Government for governmentalpurposes, without the payment to me of any royalty thereon.

This invention relates to a telescope mounting especially adapted forguns.

A telescope employed on a gun is usually mounted for adjustment so thatits axis may be moved into parallelism with the axis of bore of the gunbarrel. Due to the conditions of service the telescope must befrequently removed for cleaning and it is generally removed duringtransportation of the gun.

The purpose of this invention is to provide a simple mounting which maybe readily adjusted and which will permit application and removal of thetelescope without disturbance of the adjustment of the mounting.

With the foregoing and other objects in view, the invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed maybe made Within the scope of what is claimed without departing from thespirit of the invention.

A practical embodiment of the invention is illustrated in theaccompanying drawing, wherein:

Fig. 1 is a plan view of a telescope and mountmg.

Figs. 2 and 3 are sectional views on the corresponding lines of Fig. 1.

Fig. 4 is a sectional view generally on the line 4-4 of Fig. 2.

Fig. 5 is a reduced sectional view on the line 5-5 of Fig. 3.

Fig. 6 is a view in side elevation of the fixed frame.

Fig. '7 is a perspective of a portion of the telescope with parts insection.

Referring to the drawing by characters of reference, there is shown atelescope formed of the usual tube 5 adapted to be mounted in a frontbracket 6 and a rear bracket I attached to a gun 8. A collar 9 on thetube 5 has a rounded surface engaging the front bracket 6 whereby thetube is capable of pivotal movement.

The rear bracket I is formed with an opening for receiving a rectangularframe l (Fig. 3) which is fixed in place in any suitable manner. Thestiles I II I of the frame ID are formed on their inside surfaces withgrooves l2-I2 for mounting a sliding frame I3 (Fig. 3). A bolt l4 fixedto the bottom rail l of the frame I3 by a pin I6 is threadedly insertedin a handwheel IT.

This handwheel rests on the bottom rail I8 of the fixed frame I9 andextends beyond the side edges so as to be readily grasped. The hub IQ ofthe handwheel extends through the bottom rail I8 and receives a nutwhereby it is held against axial displacement while being free to rotateand cause displacement of the sliding frame H3. The periphery of thehandwheel is formed with notches 2! for receiving the free end of aspring V latch 22 carried by the bottom rail it of the fixed frame l0.

The inner surfaces of the bottom rail l5 and top rail 23 of the slidingframe I3v are formed with grooves 2424 for mounting a horizontallysliding block 25 (Fig. 3). A bolt 26 fixed to the left side of the blockby a pin 2i is threadedly inserted in a handwheel 28. This handwheelrests against the left stile 23 of the sliding frame I3 and extendsbeyond the side edges so as: to be readily grasped. The hub 33 of thehand-wheel extends through the stile 29 of the slidable frame andthrough a slot 3! in the left stile ll of the fixed frame and receives anut 32 whereby it is free to rotate and be displaced vertically with thesliding frame but is held against axial displacement. The handwheel 28is formed with notches 33 for receiving a spring latch 34 carried by thetop rail 23 of the sliding frame.

The sliding frame 25 is formed with a-circular opening 35 for receivingthe telescope. The wall of the opening is provided with a pair ofopposite grooves 36-36'blind at their forward ends and adapted toreceive opposite studs 3l3'I fixed on a band 38 on the telescope. Theengagement of the studs in the grooves of the block serves to hold thetelescope against forward movement as well as rotational displacement.

A rubber ring 39 fast to the inside of the band fits in an annulargroove 49 in the tube 5 of the telescope. The band and ring unitconstituting a collar is moved into position by being forced over thefront part of the tube 5.

A pair of bars 4I4I arranged oppositely to one another on the rear sideof the sliding block are each pivotally mounted on one of a pair ofbolts 4242 passing through the lower part of the sliding block. Theupper part of each bar is provided with an aperture 43 adapted toreceive a bolt 44 threadedly attached to the sliding block. A wing nut45 on the outer end of each bolt serves to retain the corresponding barin place against the block. Each bar is provided with .a lug 46 adaptedto enter one of the grooves 33 and engage and confine a stud 3? of thetelescope. The bars also engage the collar of the telescope.

When the telescope is mounted in the front bracket 6 and in the slidingblock of the rear bracket 1 it may be moved into adjustment with the gunby acting on the handwheels I! and 28 to displace the rear part of thetelescope about the collar 9 as a pivot. The provision of the rubberring permits this adjusting movement Without placing a strain upon thetelescope or the sliding block.

The position of the sliding block determines the position of adjustmentof the telescope and the position of the block is not disturbed when thebars 4| are lowered and the telescope removed.

I claim:

1. The combination with a telescope having an annular groove, a collarincluding a rubber ring fitting in the groove, and opposite studs on thecollar, of a bracket, a frame fixed in the bracket, a second framemounted for vertically sliding movement in the fixed frame, means formoving the sliding frame, a block mounted for horizontally slidingmovement in the slidable frame, said block having an opening forreceiving the collar of the telescope, the wall of the opening providedwith opposite grooves blind at one end for receiving the studs of thecollar, 2, pair of bars pivotally mounted on the block, a lug on eachbar adapted to enter a groove in the block and confine the collar studin said groove, means for clamping each bar to the block to confine thecollar of the telescope and means for moving the block.

2. The combination with a telescope, a collar on the telescope includinga resilient element and studs on the collar, of a support, a blockcarried by the support, means for moving the block on intersectingpaths, said block having an opening for receiving the collar of thetelescope, the wall of the opening provided with grooves blind at oneend for receiving the studs of the collar, bars pivotally mounted on theblock, a lug on each bar adapted to enter a groove in the block andconfine the collar stud in said groove and means for clamping each bartothe block to confine the collar of the telescope.

3. In a telescope mounting, a support, a frame fixed in the support, asecond frame mounted for vertically sliding movement in the fixed frame,a handwheel carried by the fixed frame, a bolt fixed to the slidingframe and threadedly engaging the handwheel, a block mounted forhorizontally sliding movement in the sliding frame, a handwheel carriedby the sliding frame, a bolt fixed to the block and threadedly engagingthe handwheel carried by the sliding frame, and means on the block formounting a telescope.

4. In combination, a support, a block carried by the support and havingan opening and grooves in the wall of the opening, means for moving theblock on intersecting paths, a telescope passing through the opening inthe block, a ring of resilient material embracing the telescope, a metalband surrounding the resilient ring and fixed thereto, studs on oppositesides of the band and disposed in the grooves of the block, means forretaining the studs in the grooves and means for pivotally mounting thetelescope at a position distant from the support.
